2 Early History of Jackson Brigade DNA Project October 2011 Jackson Brigade s Board approved of the Jackson Brigade DNA Project with the following goals: To establish a base of DNA knowledge for others to compare to. To find cousins to whom we could reach out and invite to become members of Jackson Brigade. To gather DNA evidence to aid in proving family connections of interest to the Jackson Brigade. November 2011 We identified two direct line Jackson males who are descendants of John Jackson and Elizabeth Cummins but from separate Jackson lines - John M. Jackson (Henry Line) and Robert Lee Jackson (John Jr. line). John and Lee took Y-DNA 67 tests. January 2012 We discovered interpreting test results were daunting! Summer 2012 To unravel the meaning, Dan Hyde studied DNA testing. July 2012 Dan created a DNA Project web page on which he posted and explained the results of John and Lee s Y-DNA tests. Some background in DNA testing before explaining the results. Dan Hyde Recent Results from DNA Project 2

4 Facts about Nuclear DNA 23 pairs of Chromosomes make up Nuclear DNA Over 3 billion base pairs or nucleotides. Adenine (A), Cytosine (C), Guanine(G), and Thymine(T) DNA is a long sequence of nucleotides. The A-C-G-T letters Single Nucleotide Polymorphism (SNP) snip a small genetic change that occurs within a DNA sequence, e.g., an A to a G. Occurs infrequently, e.g., once in several thousand years - used to determine your Haplogroup (your ancient ancestry). All humans share 99.5% of same DNA. Dan Hyde Recent Results from DNA Project 4

5 Y-DNA test Men pass on their Y-chromosome only to sons. Test looks at markers on man s Y-chromosome. Can test 12, 25, 37, 67, 111 markers. Markers are Short Tandem Repeats (STR) In a non-coding region, a pattern such as AGAT is repeated. E.g., AGATAGATAGAT has 3 repeats. STRs mutate relatively fast, say, once in 150 years. Ex: marker DYS 393 is known to repeat AGAT from 9 to 17 times. John and Lee Jackson both have a 13. Only males can take a Y-DNA test. Y-DNA 67 test costs about $265 per male.

6 More on Y-DNA Test Advantage: Y-DNA follows surname path in most cultures. Limitation: Only supplies information on a few ancestors! Ex: 5 generations back, a male has 62 ancestors (parents, grandparents, etc.). Y-DNA test is only useful for the six direct males (man, his Dad, his Dad, etc.). Y-DNA testing provides no information on the other 56 ancestors! A test result on its own reveals little. Matches with others are key! Y-DNA test is still very useful! - Can verify paper trail along surname path. - Can show two surname lines are closely related. - Can help determine father in an adoption or illegitimacy case. - Can help identify the Most Recent Common Ancestor (MRCA).

8 Y-DNA Results of John M. and Lee First 25 markers of 67 for Lee Jackson (first line) and John M. Jackson (second line): 66 of 67 markers are the same. Marker DSY534 differs. Lee: 14 John: 15 66/67 means with 95% probability MRCA in last 8 generations. From paper trail: Lee is descended from John Jackson, Jr. and 6 generations from John Jackson. John M. is descended from Henry Jackson and 8 generations from John Jackson. Confirms paper trails for both Lee and John M. to John Jackson no hidden adoptions, hanky-panky, surname changes, or major research errors. Confirms John Jackson s Y-DNA and all his direct male descendants including Thomas Stonewall Jackson. Confirms John Jackson s Y-DNA for matches to his direct male ancestors, e.g., his father, grandfather, etc. However, none found so far! But we are hopeful! Dan Hyde Recent Results from DNA Project 8

9 Direct Male Lines of John Jackson John Jackson = Elizabeth Cummins George Edward John Jr. Elizabeth Sophia Mary Sara Samuel Henry 5 generations later Robert Lee Jackson 7 generations later John M. Jackson All the direct males (in blue) share the same Y-Chromosome with possible mutations. Since 66 of the 67 markers of John M. and Lee are the same, there is one mutation somewhere up the chain from Lee to John Jackson and down the chain to John M. Dan Hyde Recent Results from DNA Project 9

10 Other Sons of John Jackson? After listening to my DNA talk at the 2016 Reunion, Ted and Betsy Wieber identified Franklin Frank Earl Jackson, a direct-male descendant of Betsy s ancestor Col. Edward Jackson. Frank agreed to take a Y-DNA 67 test. A little later, Branch Advocate Juliann Lumpkin identified Lowell Wayne Jackson of the Samuel Jackson line. Wayne agreed to take a Y- DNA 67 test. Much like the first two tests, the new Y-DNA test results confirm the paper trails back from Frank and Wayne to John Jackson are correct! Important news for the Edward and Samuel Jackson descendants! That covers four of the five sons of John Jackson. We have yet to identify a living direct male Jackson of the George Jackson line to ask him to take a Y-DNA 67 test. Dan Hyde Recent Results from DNA Project 10

11 Y-DNA Test Results from Four of John Jackson s Male Lines Frank s Y-DNA matches 66 of the 67 markers with John M. and 65 of the 67 markers with Lee. Wayne's Y-DNA matches 65 of John M.'s 67 markers. Below is a table of the three Y-DNA 67 markers that are different among the four tested individuals. The other 64 markers are the same for all four men. Kit# Name of Tester CDY DYS413 DYS534 Descends from John M. Jackson Henry Jackson Robert Lee Jackson John Jackson Jr Franklin Earl Jackson Edward Jackson Lowell Wayne Jackson Samuel Jackson This is consistent with one Y-chromosome mutation on the branch from our ancestor John Jackson to Lee; one Y-chromosome mutation on the branch from our ancestor John Jackson to Frank; and two mutations on the branch from our ancestor John Jackson to Wayne. This implies the new conclusion that our ancestor John Jackson had the exact same values of the Y-DNA 67 markers as John M. Jackson! Dan Hyde Recent Results from DNA Project 11

13 Jackson Ancient Ancestors and Clan A Y-haplogroup is a group of males with a common (possibly ancient) direct-male ancestor. Direct-male means along the male line, e.g., father to son, to his son, etc. Since 2012 we have known John and Lee s Y-DNA haplogroup to be R1b1a2 (also R-M269). All males with the defining M269 mutation on their Y-Chromosome are placed in this Y- haplogroup. Unfortunately, the R-M269 haplogroup is the most common European haplogroup! It s huge with millions of living men in it! It is estimated to contain 110 million Europeandescent men. "The age of the mutation M269 is estimated at roughly 4,000 to 10,000 years ago, and its subclades [sub-trees] can be used to trace the Neolithic expansion into Europe as well [as] foundereffects within European populations due to later (Bronze Age and Iron Age) migrations."

16 Narrowing Down the Haplogroup Being grouped with 110 million other men doesn't provide much insight into one's own personal history! We want to identify much smaller sub-groups of this huge R-M269 haplogroup and be able to place individuals such as our ancestor John Jackson in the proper sub-group. Big Y Project: Genetic scientists from all over the world are actively working towards this goal! New advances in this genetic research area are happening almost daily. Dan Hyde Recent Results from DNA Project 16

17 How to Narrow the Haplogroup? Has mutation 1? no yes Large Haplogroup Has mutation 2? no yes Has mutation 4? no yes Has mutation 3? no yes Many smaller haplogroups The idea is to branch off a sub-group whenever a defining mutation of the Y-Chromosome occurs and place all the descendants with the defining mutation in the new sub-group. Continue to do this splitting into smaller haplogroups. This forms a HUGE tree structure potentially holding all men living now and in the past. Called the Big Y Tree. The chain of defining mutations for John Jackson would be: R > R1 > R1b > > R M269 Dan Hyde Recent Results from DNA Project 17

18 John Jackson s Ancient Ancestral DNA Roots We took this journey of discussing haplogroups and chains of defining mutations on the Y-Chromosome hoping to gain insight into John Jackson's ancient ancestral DNA roots. We gained this valuable insight when Ted and Betsy Wieber paid to have further DNA testing (SNP testing) on Frank Jackson's Y- DNA sample to refine Frank's haplogroup. The result extends the chains of defining mutations for Frank: M269 > L23 > L51 > U106 > L48 > Z9 > Z30 > Z2 > Z7 > Z8 The important fact for us is that Z8 is the final haplogroup in the chain. Since Frank is a direct-male descendant of our ancestor John Jackson, there is a very high probability that John Jackson is in haplogroup Z8 and all of his direct-male descendants are as well. Think of Z8 as John Jackson s clan. Dan Hyde Recent Results from DNA Project 18

19 John Jackson s Ancient Ancestral DNA Roots Some quotes on the Z8 clan. One website states that "... the haplogroup of R-Z8, a subgroup of R-M269, that branched off perhaps 2000 years ago from European Germanic tribes, [that arrived] in the British Isles with the 5 th -century AD Germanic invasion (all this is still uncertain)." A second website states "Z8 - Age approx.: 1234 BC (range: 1758 BC BC). Common around the western Baltic from where modern Germanic peoples spread from around 700 BC, Z8 represents the outcome of a major population collapse then expansion, perhaps associated with the late Nordic Bronze Age or at the start of the Iron Age around BC."

20 John Jackson s Ancient Ancestral DNA Roots Note: The company Family Tree DNA has recently updated Frank's Y-haplogroup to R-BY41552, a smaller sub-group of Z8. So they have determined a smaller clan for Frank, whose common ancestor lived closer to our present time. However, this common ancestor of the R-BY41552 clan probably lived before surnames were used (Surnames started in England about 1200 A.D.) Probably because it's a newly designated haplogroup, I have found nothing to report on the R-BY41552 clan. Dan Hyde Recent Results from DNA Project 20

21 Summary These are exciting times for genetic science and genealogy! We are on the sidelines watching as the genetic scientists make great strides in piecing the puzzle together to explain how humans spread across our planet from eastern Africa. Soon the genetic scientists will refine the haplogroups ( clans ) to a point where they will be able to match an individual's written records. This is already being accomplished for a few royal families, e.g., the Bourbon Kings (see When this happens on a broader scale, many brick walls will fall!
